So it is true that you cannot use Emacs with only one hand.
The only downside is that you can't embed images in info, so you end up lots of ASCII art flowcharts ava box drawings. But that's true of man pages as well.
The Guix manual, for example, has a couple of images that you can see inline in the Emacs info reader.
Personally I have no problem to navigate info because I learned that before HTML was invented. Of course today many people don't accept the idea that one would need to learn such tool. Well, luckily they can read the same content on the Web in various layouts. Working offline is not a very common requirement.
